MSP Spark plug options

[dirtysouth_msp]

are bkr6e-11 plugs ok for the msp? the lady at checkers said it would be better for my car. i am currently running the bkr7e and my car does not like them at all. i'm at stock boost.

If you are mostly stock and running stock boost, the bkr6e is probably better. Unless you are constantly in boost or constantly running at high RPM's, the colder plug (7 heat range) will probably foul out faster and may cause idle issues.

Hope that helps.

I just ordered a set of the denso IK22's and have a question. I ordered them from a speed shop and they don't know what the gap is on the plugs. Does the IK22 only come with .032? I just checked sparkplugs.com and they said that the ik20's fit our cars the ik22 do not. Can someone help me out with this.

Thanx

I'm having the same dilemma. Evidently, the IK20 is considered the stock replacement because it's the stock heat range. The IK22 is slightly colder. I don't know how much it would matter for me with stock boost and during the winter. However, my Vibrant exhaust is going on this weekend and a Turbohoses SMIC is going on a few days after that, and both of those items are reported to raise boost a bit. I'll probably just suck it up and order the IK22's, but I'm tempted to get the IK20's since the Autozone down the street has them in stock right now for $12.99 each.

I dunno man. I usually get burgers and chilli cheese fries at checkers. I don't really ask them for spark plug advice.

Yeah, the Denso site says that the IK20 fits our cars but they come gapped at .42 and we need a gap of .32 at stock. So I don't think the IK20s will work. But the IK22s come pre-gapped at .32 and running a level colder is not a bad thing at all. I've heard from a few guys on here that their cars run great with the IK22s and hopefully they too are stock because all I've got a a custom intake and I just ordered a set of the IK22s today.

i got mine at a performance shop for $10.10 a peice and they came in today pregapped at .032

they run much better than the stock NGK plugs

Which ones did you get?? The IK20 or IK22??

IK22's

 

[srvntfhim]

IK22's

Oh good. That's a relief. I thought I ordered the wrong plugs a second time! I ordered the IK20s first and then realized they weren't pregapped to .32. So I ordered the IK22s today and sent the IK20s back.

I broke down and bought a set of IK20's from my local Autozone. They were gapped at between .040 and .045, but I regapped them to .032-.034. I haven't even started the car yet, since it's the middle of the night and my g/f is asleep above the garage, but I'm assuming they'll be fine. I would have felt more comfortable with the colder IK22's, but I have a limited window to get all the work done on my car right now. I'm going to take it out for a spin in the morning and I'll let you know if I can tell a difference. My 42k mile originals looked pretty good. They had a definite red cast to them though.

Not sure about the IK20's, but it said right on the box of my IK22's that you should not even try to gap these plugs. It says that you will most likely break them or throw them off-center. If you experience problems with the plugs, that is probably going to be the culprit. (poke)

Lovely. Didn't even catch that. I was very careful about it though, and just slowly worked them down. I can't imagine I threw them off too much going down 8 or 10 thousandths. We'll find out. About to head out for a while and see how it runs now.

Well, no huge butt dyno power gains, but it's definitely smoother. The first thing I noticed pulling out of the garage was that it only took a touch on the gas pedal to get it moving. All around town I noticed it was more responsive and didn't seem to need as much throttle. Surely my gas mileage is going to improve a bit as well. I've been tracking it this Winter at 28-29 mpg in mixed driving, so I'll know if it gets any better.

Cool, glad that worked out for you.

I am curious if the dyno would show a difference, but it's not worth $65 to find out if the plugs helped any. I just baselined the other day at 143/160, which seemed a few hp low and that was on the original plugs with 42k miles on them.

I just installed my IK22s last night. Wow...what a difference!!

I also noticed a night and day difference with mine. I also went from having my fuel light turn on around 275-285 miles on the tank to it not coming on until 310 miles on my last fill up. So it's nice to get another 40+ miles to the tank just by changing the plugs

 

[HeHateMe]

In your guys opinion, should i go with IK20's, or IK22's.

 

[Theninemilly]

if running stock boost the IK20's should be fine. If you up the boost at all I would go with the IK22's. I think that's the theory here. I went to the Ik22's and have the unichip and it works great

 

[Tommy1005]

I also have switched to the IK22's now and as stated above, they are worth the money if your running upped boost
